Compound microbial fertilizer for preventing continuous cropping of ginseng and preparation method thereof

Abstract

The invention discloses a compound microbial fertilizer for preventing continuous cropping of ginseng. The fertilizer comprises an organic fertilizer, an inorganic fertilizer and compound functional bacteria, wherein the organic fertilizer comprises Chinese medicine residues, humic acid, diatomite, pelelith, bentonite, zeolite, charcoal, grain byproducts, sugar, enzyme microorganisms and water; the grain byproducts are bran or rice bran; the inorganic fertilizer comprises potassium nitrate, urea, potassium dihydrogen phosphate, potassium sulfate and potassium fulvic acid; the compound functional bacteria comprise acinetobacter, variovorax, streptomycetes and trichoderma sp. The compound microbial fertilizer is an organic, inorganic and biological ternary compound fertilizer. The fertilizeralso contains biological stimulin such as humic acid and fulvic acid and trace elements in natural mineral sources. The fertilizer for ginseng production has the effects of promoting growth and development, improving output and reducing diseases, can prevent influence of auto-toxic matters caused by allelochemicals secreted by ginseng root systems, and prevents continuous cropping of ginseng favorably.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to a compound microbial fertilizer for preventing repeated cropping of ginseng and a preparation method thereof. Background technique [0002] Ginseng (Panax ginseng C.A.Mey.) is a perennial herbaceous plant of the genus Panax ginseng in the family Araliaceae. , the garden ginseng is called raw sun-dried ginseng after drying and drying, and red ginseng after steaming and drying; The roots, flowers and seeds of ginseng all have high medicinal value and economic value. Artificially grown ginseng belongs to the "medicine and food homology" plant. Jilin Province is the main production area of ​​ginseng in my country, accounting for about 85% of the national ginseng cultivation area. Jilin is also the largest ginseng artificial planting area in the world, accounting for about 70% of the global area. The measures to limit the planting of ginseng in forest land h...

AI Technical Summary

Problems solved by technology

At present, there are not many researches on microorganisms degrading ginseng allelochemicals at home and abroad, which are still in the initial stage and at the laboratory level. Pot experiments are limited to the direct application of microbial agents cultivated in laboratories, and the results of follow-up experiments are not sufficient.

Ordinary biological fertilizers and compound microbial fertilizers are used as ginseng cultivation to improve soil, fertilize soil fertility, enhance stress resistance, promote growth and development, and increase yield. Requirements for ginseng growth and high yield, and has no significant effect on the obstacle of ginseng cropping

However, the simple application of chemical fertilizers and compound fertilizers can provide sufficient nitrogen, phosphorus and potassium elements, but due to the lack of organic matter and trace elements, it will be unfavorable to soil physical and chemical properties and soil microbial flora, and will cause a series of growth and development obstacles.

That is to say, the combined use of organic fertilizer, compound fertilizer and biological fertilizer has been achieved, but there are problems such as troublesome application and large dosage
